FILTER.

Specification of Letters Patent.

Patented. April 23, 1907.

Application filed March 3, 1906. Serial No. 304,105.

To (LZZ w/wne it may concern:

Be it known that I, l/VILLIAM J. ARCHER, a citizen of the United States,residing at Brighton township, in the county of Beaver and State ofPennsylvania, have invented certain new and useful Improvements inFilters, of which the following is a specification, reference being hadtherein to the accompanying drawings.

My invention refers to improvements in filters, more particularlyfilters for domestic use and is designed. for the purpose of providing adevice of this character which will be simple and cheap in construction,efficient in operation, capable of being readily taken apart andcleansed or re-assembled, of economical manufacture, and providingfacility for inspection of the interior at all times.

The invention comprises generally a middle frame adapted to receive andsupport a filtering stone or material at its middle transverse portion,adjacent removable cylinders of glass or other suitable material, asurrounding frame, with packing devices and mechanism for clamping theparts tightly together; also a rotating cleaning, scraper; means forintroducing the supply water; means for drawing off the scouring orcleaning water and sediment, and means for withdrawing the filteredwater, as shall be more fully hereinafter described.

Referring now to the drawings; Figure 1. is a view in front elevation ofmy improved sectional view thereof on the line II. II. of separablewater filter. Fig. 2. is a vertical Fig. 1. Fig. 3. is across sectionalview on the line III. III. of Fig. 1.

2 represents a middle stone bearing body portion of the filter which maybe cast metal or other suitable material having at its middle interiorportion a seat 3, preferably tapered, for receiving and holding thefiltering stone or material 4. This stone, which may be Tripoli stone,is merely set in the tapered seat by making a tight grinding fittherewith without the use of any holding cement or other means, or itmay, if preferred, be setinto the receiving seat without any preliminaryfinishing, using an intervening body of cement or other plastic materialcapable of hardening.

Tapped into one side of the stone holding portion 2 is the withdrawalfaucet 5 for carrying oil' the dirty Water and accumulated impuritiesfrom above the filtering stone, and stone being cut down at one edge orperforated from the top outwardly to the side as indicated at 6 toprovide an aperture registering with the faucet.

7 and 8 are water enclosing shells, preferably formed of heavy glasscylinders seating against the upper and lower faces of the stone bearingbody portion 2 with intervening packing gaskets 9 of rubber or othersuitable material, which cylinders are tightly clamped against thesebearings by means of the surrounding yoke 10. Said yoke bears upwardlyagainst the bottom portion of lower cylinder 8 as clearly shown, with anintervening packing gasket 11. An outlet nipple 12 is passed through thebottom portion of the yoke, extending upwardly into the interior of thelower cylinder 8, with the bottom portion of which it makes awater-tight joint by means of an intervening gasket 13, it beingunderstood that a suitable opening is provided in the bottom of cylinder8 downwardly through which the nipple 12 extends. 14 is a withdrawalfaucet for the filtered water connected with nipple 12 in any suitablemanner as by means of an intervening elbow 15.

16 is a water inlet nipple threaded. around its exterior as clearlyshown, tapped through the upper internally threaded terminal 17 of yoke10 and bearing downwardly against the upper end of cylinder 7 by meansof an inter vening washer 18 and. packing gasket 19, as clearly shown inFig. 2. The nipple 16 is provided with a nut extremity 20, and it willthus be seen that by turning said nipple the entire apparatus may betightly clamped together so as to make a fluid-tight constructionthroughout.

Connected with the upper portion of nipple 16 by hollow pipe fittings orother mechanism of any suitable construction, is the inlet faucet orcock 21 controlling the supply of water to the filter from pipe 22, although ordinarily this faucet may be kept open to utilize the waterpressure at all times except when it is desired to take the apparatusapart. The upwardly extending fittings or connections between the nipple16 and inlet faucet 21 may be of the construction shown, or may, ifpreferred, be a single integral cast section; and with eitherconstruction is provided at its upper portion a stuffing box 23providing for insertion of a rotatable scraping shaft 24. This shaft isprovided at its upper portion with a handle 25 and scraping blades 26 orother suitable devices at the lower end whereby the upper surface of thefiltering stone may be cleansed from impurities or sediment depositedfrom the Water.

As shown, the embracing yoke 10 isengaged by projecting guides 27extending from the middle section 2 whereby these ports are maintainedin alinement.

When assembled in this manner the entire apparatus is very compact,provides for all of the various functions necessary or desirable in adevice of this character, while the interior of the filter may be viewedthrough the glass cylinders at all times. This latter feature of thedevice is an important and valuable one, as it permits of observation ofthe internal condition without the necessity of first taking theapparatus apart.

A further feature of advantage is that the glass cylinders avoid thenecessity of internal finishing while they protect the metallic partsfrom corrosion and are readily and easily cleansed.

The apparatus may be of various sizes, forms or design; it is veryefficient in opera tion, simple and economical in construction and notliable to get out of order, and is well adapted to the objects in view.It may be changed or varied by the skilled mechanic in various detailsof construction, within the scope of the following claims.

Having described my invention, what I claim is:

1. In a filter, the combination of a middle stone bearing portionprovided with a filter ing medium, upper and lower cylinders seatingagainst said portion with intervening packing devices, a surroundingclamping yoke bearing against the outer end of the lower cylinder, athreaded tube engaging the upper end of the yoke and bearing against theend of the upper cylinder, a water supply device communicating with saidtube, and means for withdrawing water from the interior of saidcylinders, substantially as set forth.

2. The combination of a transverse diaphragm of filtering material, anenclosing housing therefor, cylinders arranged to bear against oppositesides of said housing with intervening packing gaskets, water supplymechanism connected to one of said cylinders, a withdrawal faucetconnected with the other of said cylinders, and a separable embracingyoke arranged to exert pressure against the outer end of each cylinder,substantially as set forth.

3. The combination of a transverse diaphragm of filtering material, anenclosing housing therefor, cylinders arranged to bear against oppositesides of said housing with intervening packing gaskets, water supplymechanism connected to one of said cylinders, a withdrawal faucetconnected with the other of said cylinders, a rotatable cleaning deviceprovided with a rod extending through said water supply mechanism,packing devices therefor, and a separable embracing yoke arranged toexert pressure against the outer end of each cylinder, substantially asset forth.

4. The combination of a transverse diaphragm of filtering material, anenclosing housing therefor, cylinders arranged to bear against oppositesides of said housing with intervening packing gaskets, water supplymechanism connected to one of said cylinders, a withdrawal faucetconnected with the other of said cylinders, a withdrawal faucetconnected with the filtering material housing, and a separable embracingyoke arranged to clamp the cylinders against the housing, substantiallyas set forth.

5. The combination of a transverse diaphragm of filtering material, an,enclosing housing therefor, cylinders arranged to bear against oppositesides of said housing with intervening packing gaskets, water supplymechanism connected to one of said cylinders, a withdrawal faucetconnected with the other of said cylinders, a withdrawal faucetconnected with the filtering material. housing, and a separableembracing yoke arranged to clamp the cylinders against the housing,.with intervening packing devices, substantially as set forth.

6. The combination of a transverse diaphragm of filtering material, anenclosing housing therefor, cylinders arranged to bear against oppositesides of said housing with intervening packing gaskets, water supplymechanism connected to one of said cylinders, a withdrawal faucetconnected with the other of said cylinders, a withdrawal faucetconnected with the filtering material housing, and a separable embracingyoke arranged to clamp the cylinders against the housing, with arotatable cleaning rod provided with a scraping extremity, said rodextending through the water supply mechanism, and a stuffing box forsaid rod, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
